Financing new single-family home construction - full repayment, building savings contract, or annuity loan?

So we are well above your planned costs with significantly less living space and do a lot ourselves.
But Greater Munich also has different prices.

We are located very rurally, which is also reflected in the land price (although prices have increased quite a bit here as well).
Thank you for your assessment. :)

One more small "interjection". 223 sqm living space, are you sure? It might well be that no children come along either, that was the case with the second child for us. What then? You are not in the best childbearing age. Just something to think about. 170-180 is also completely sufficient, even for 4 people.

It was planned smaller, but due to the desired floor plan and the fact that we have living space in the "basement", it is now a few sqm more. However, it would be possible to separate the attic and rent it out as a separate apartment or use it otherwise.

Otherwise, the financing and construction costs look great. Should work out.
Many around us also built 250 m² + double garage for 250-300k.

Thank you very much for your assessment and helpful comments. :)

Hello, I would evaluate the construction costs seriously and not use a local index. That can never keep up with the current trend.

The index is issued annually, of course it can only reflect an average. If I want to build top class, that won’t work with the given value; one should realistically see that.
Additionally, an employee from one of the financial providers reviewed it and was also satisfied with it (although I wouldn’t necessarily consider that reliable). With the first offers we have received so far, we are each time below the calculated amounts.

I am a big fan of safe, simple, and straightforward, and would therefore take the first offer.

I don't think much of building savings contracts. Friends of ours financed that way, and when it was actually time for the payout, the valuation number of the building society was not reached (which, as far as I understand, one has no influence on, but is set by the BSK). They then had real stress and had to arrange interim financing.

You can compare the total costs of all the offers.

For me personally, the security of full repayment would be important. I also find the interest rate of Allianz good.
And if interest rates go down again, you can cancel after 10 years and refinance.
